Charles Spurgeon Commentary 1 Chronicles 15:14-16

"So the priests and the Levites sanctified themselves to bring up the ark of Jehovah, the God of Israel. And the children of the Levites bare the ark of God upon their shoulders with the staves thereon, as Moses commanded according to the word of Jehovah. And David spake to the chief of the Levites to appoint their brethren the singers, with instruments of music, psalteries and harps and cymbals, sounding aloud and lifting up the voice with joy." — 1 Chronicles 15:14-16 (ASV)

Before, there had been a great medley of musical instruments, but little singing, and there had not been a proper choice as to the persons who were to sing; but, now, this service was put into the right hands. Then follows a list of the singers and the players upon the various kinds of instruments that went forth to bear the ark. Let us pass on to the twenty-fifth verse.
